In response to a number of points made here:
1. Nadel completed her BA at Georgetown. She has eligibility remaining.
2. She might actually have more than a year left. Her TFRRS is pretty sparse and I obviously don't have access to her medical records but if she didn't compete at Big East or any other post season competition due to injury shoe might be able to get second medical hardship waivers and have a 6th year.
3. I'm fairly certain Oregon has some masters' programs that can be completed within a year. Other schools do to--I recall Juliet Bortoff staying an extra year and Duke and being able to complete a one-year MBA program there. Some of them do this by using the summers in addition to the September-May academic year, some just don't have as many credits.
4. It's actually kind of surprising to me that Brianna Nerud's experience at Oregon would motivate Nadel to follow her there. I do not know why Nerud transferred there from Syracuse to begin with but she had seemed to be doing well there. She went to Oregon and actually never made it back to NCAAs. She was the lone freshman to qualify in the steeple in 2013.
5. Nadel actually has not been an All-American at Georgetown that many times. In 2015-2016 she didn't compete at NCAAs in any of the three seasons--she probably qualified outdoors but must have been injured as her only race was Stanford.
In 2014-2015 she was a cross country All-American and an All-American indoors but didn't compete during outdoor.
In 2013-2014 she was probably a cross country All-American (47th), she didn't run indoors, and her season ended at the NCAA East Prelim.
In 2012-2013 she was not an All-American--126th in XC, didn't even run at Big East indoors, season ended at the NCAA East Prelim outdoors.
Looking at that it actually makes more sense that she does want to go elsewhere. She's run very well when she's healthy BUT it's rare that she is healthy. There was more than one XC season where she didn't run until Big East. I can feel her frustration.
